Support ByteCount in plugin parser

[dlvenable]

Is your feature request related to a problem? Please describe.

Plugin authors must use strings and manually convert to use ByteCount in their configuration files.

Describe the solution you'd like

Support ByteCount deserialization in the plugin parser. This would be similar to the data-prepper-config.yaml which supports it already. And it would give similar to behavior to the duration deserializer.

Additional context

Needs to be added here:

data-prepper/data-prepper-core/src/main/java/org/opensearch/dataprepper/plugin/PluginConfigurationConverter.java

Line 37 in 59c48e2

simpleModule.addDeserializer(Duration.class, new DataPrepperDurationDeserializer());

Compare with:

data-prepper/data-prepper-core/src/main/java/org/opensearch/dataprepper/parser/config/DataPrepperAppConfiguration.java

Lines 34 to 36 in 35e37c6

	final SimpleModule simpleModule = new SimpleModule()
	.addDeserializer(Duration.class, new DataPrepperDurationDeserializer())
	.addDeserializer(ByteCount.class, new ByteCountDeserializer());

Hi @dlvenable , Could you please assign me this.

[dlvenable]

@Durdush , Thank you for your interest in working this! Do you have any questions about how to accomplish it? I believe I have some information in the description to get started on it.

Hi, is this issue still relevant? I can submit a PR to address this.
Seems that it supported in pluginConfigObjectMapper but not in extensionPluginConfigObjectMapper.

data-prepper/data-prepper-core/src/main/java/org/opensearch/dataprepper/plugin/ObjectMapperConfiguration.java

Lines 40 to 43 in 553b4c1

	ObjectMapper pluginConfigObjectMapper(final VariableExpander variableExpander) {
	final SimpleModule simpleModule = new SimpleModule();
	simpleModule.addDeserializer(Duration.class, new DataPrepperDurationDeserializer());
	simpleModule.addDeserializer(ByteCount.class, new ByteCountDeserializer());

data-prepper/data-prepper-core/src/main/java/org/opensearch/dataprepper/plugin/ObjectMapperConfiguration.java

Lines 30 to 37 in 553b4c1

	ObjectMapper extensionPluginConfigObjectMapper() {
	final SimpleModule simpleModule = new SimpleModule();
	simpleModule.addDeserializer(Duration.class, new DataPrepperDurationDeserializer());
	return new ObjectMapper()
	.setPropertyNamingStrategy(PropertyNamingStrategies.SNAKE_CASE)
	.registerModule(simpleModule);
	}

I can use #3326 as reference since it's been a while since it's been active.

@GumpacG,

This was partially resolved in pluginConfigObjectMapper as you noted. However, this will not be available until 2.7.0.

https://github.com/opensearch-project/data-prepper/pull/3958/files#diff-ada28b8b3eeeba5a7e1e322dcff5b6b90a3a79c174f011609f826972f1f302dcR38

I don't think we resolved this in extensionPluginConfigObjectMapper yet. Feel free to create a PR to finish it up. Thanks!
